A Dynamic Voltage-Reliant Framework for Voltage Regulation Using Synchronous Condensers, SVCs, STATCOMs, Feeders Switching, and Distributed Unit Commitment

Effective decrease in losses and bus voltage deviation within distribution grids can be attained using grid switching (GS), placement of capacitors (C), or optimal distributed units commitment (DU commitment), in which consumers play crucial roles in this optimization processes. However, simultaneously performing dynamic GS and DU commitment (DUC), as well as coordinating the reactive power output of dynamic devices such as synchronous condensers (SCs), static synchronous compensators (STATCOMs), and static VAR compensators (SVCs), can considerably improve the grid’s voltage profile and reduce power losses under fluctuating conditions. Also, accurate load modeling is fundamental for analysis, as the situation of continuously fluctuating loads with respect to voltage directly impacts the energy dissipation and voltage regulation. This, in turn, influences control of GS, SCs, STATCOMs, SVCs, and DUC. Since representing the load versus its components is actually significant, this paper presents a flexible dynamic mixed-integer binary framework to anticipate more confidant and secure coordinated controls for GS, SC, STATCOM, SVC, and DUC to regulate the system’s voltage. The study is conducted on an example 14-bus distribution network and the standard 33-bus grid via the mathematically formulating components of load versus type of consumer along with reactive and active power generation based on voltage fluctuations. The findings demonstrate appropriateness of the presented framework for regulating voltage in distribution systems.
